Could you tell me if you have any plans to enable Ubuntu on the Raspberry Pi (ARMv6) ?

Short answer: an Ubuntu ARMv6 port for the Raspberry Pi isn't a Linaro target, but we're taking patches and we're interested in some bugs! :-)

There are two main reasons for that:

• Linaro doesn't have the capacity to do large scale distro ports, this is usually mainly the job of distros, and we're sometimes giving a hand
• Linaro is all about the future of ARM, so the focus is mainly on ARMv7 and ARMv8 at this point

That said, there is hope! First, a bunch of Linaro folks have a Raspberry Pi and play with it; second, I believe Ubuntu's armel port is being re-targeted to ARMv5, so Ubuntu armel binaries should eventually run on the Pi.

Yip. There's an unsupported cross compiler for Raspbian at: https://launchpad.net/linaro-toolchain-unsupported/+download

Linaro does directly care about toolchain regressions you might encounter on ARMv5/ARMv6 (or even on x86), so please do report us any toolchain regressions caused by Linaro patches.

Yes please. While we're focused on the Cortex-A series, we don't want to harm earlier architectures. If you see any speed or correctness regressions please let us know.

  Cheers,

As far as distros go, there's also a Fedora 17 remix for the Raspberry Pi:

Works pretty nicely on my Pi. It's not the Linaro toolchain per se, but just like Loic says, any toolchain regressions are of interest to all of us -- improving Linux on ARM is the point of the exercise.
